Consideration of the heat exchanger-air cooler clogging

The feasible solutions of the air coolers clogging are discussed. The most promising research directions are defined and necessary conditions for their realization are formulated. The experimental simulation of nonclogging conditions on the heat exchanger surface is accomplished. The theoretical model of frost formation based on the hypotheses of temperature gradient constancy over frost layer thickness and absence of moist air supersaturation in the boundary layer has been proposed. The mathematical simulation of the flow and heat- and mass transfer processes under frost formation in the plane cooled channel are performed using the integral calculation method by Kutateladze and Leontyev for boundary layer and the theoretical model offered.
